7 Claims. (Cl. 5 13) This invention relates to convertible or pull-outbeds and is directed particularly to improvements in the pulloutmechanism for such beds. Pull-out beds of the type contemplated by theinvention comprise a head section pivoted to a bed, couch or sofa frame,an intermediate or main section pivoted to the forward end of the headsection, a fold section pivoted to the intermediate section, and a footsection pivoted to the fold section, said sections being foldable orfully collapsible into the frame.

One diiculty with the pull-out beds of the type herein considered hasbeen that the mattress which has to be folded with the folding sectionswhen the bed is collapsed or folded has a tendency to open up the foldedbed. Accordingly, one object of the present invention is to provide ahighly improved lockingu means for holding the folded foot and foldsections in closed relation with respect to the intermediate or mainsection when the bed is collapsed so that the compressed mattress willnot have any tendency to open the folded bed. Another Object of thisinvention is to provide a bed of the type described which embodiesimproved folding mechanism whereby the bed can be folded into a sofa orcouch frame of lesser depth than heretofore possible.

Another object of this invention is to provide a conv ertible bed of thecharacter described wherein the folding mechanism is located beneath themattress when the bed is in extended position so as not to interferewith comfortable sitting on the bed when extended.

Another object of this invention is to provide a pullout bed which is soconstructed that when the foot section is swung upwardly it will pivotabout the front end of the fold section, means being provided to preventthe fold section from swinging upwardly relatively to the foot end ofthe intermediate or main section until the foot section is at apredetermined angle relative to the fold section. At such time both thefoot section and the lfold section must be swung together relative tothe front end of the intermediate or main section to a position wherethe fold section is at right angles to said intermediate or mainsection, said foot section then being above the main or intermediatesection and pitched somewhat downwardly to provide a correct angle for aseat pillow placed on said foot section after the bed is fully foldedinto the couch or sofa frame.

Another object of this invention is to provide a folding bed of thecharacter described having means to prevent the downwardly pitched footfrom being swung upwardly relative, to the fold section in an unfoldingdirection, the construction being such that said downwardly pitched footsection and the fold section will unfold together by swinging withrespect to the outer end of the fold section.

A further object of this invention is toprovide a folding bed of thecharacter described having means permitting the head section to be swungdownwardly and backwardly about its pivot point to the couch or sofaframe, thereby moving the main or intermediate section with the fold andfoot sections over Vthe footboard United States Patent ICC at the frontof the frame and deep into said frame, highlyimproved locking meansbeing provided to lock the folded fold and foot sections to theintermediate or main section during such movement into the frame.

Still another object of this invention is to provide an improvedpull-out bed which is easy to operate and which has positive lockingaction for locking the folded foot and fold sections to the main orintermediate section when the bed is fully collapsed or folded into itscouch or sofa frame.

Another object of the invention is to provide folding bed mechanism ofthe character described having a transverse bracing bar structureconnecting each side of the short fold section which, when the bed is inextended or pulled-out condition, is located sufficiently below the bedspring and mattress so as not to obstruct downward movement of thespring and mattress when a person sits over the fold section.

Still other objects of this invention are to provide a convertible couchor sofa bed of the character described which shall be inexpensive tomanufacture, easy to manipulate and which shall be practical andefficient to a high degree and use.

Other objects of this invention will in part be obvious and in parthereinbelow pointed out. f

Referring now in detail to the drawings, 10 designates a pull-out orsofa bed embodying the invention. The same comprises a sofa or couchframe 11 and a collapsible or foldable bed 12 mounted thereon andcollapsible or foldable thereinto. The couch or sofa frame 11 maybepmade of wood or any other suitable material, and comprises a rearwall 14 and side walls 15 forming an enclosure within which the bedfolds when in folded condition.

Fixed to the Ainside of the side walls are brackets 20. Each bracket isZ-shaped and has a flange 21 attached as by bolts 22 to wall 15.Extending from flange 21 is a web portion 23 from which extends upwardlya flange 24 parallel to wall 15 and spaced inwardly therefrom. Saidflange 24 carries a pivot pin 25. Pivoted on the pivot pin 25 is one endof a right angular side member 25a. The other end of said side member ispivoted to the head section of the folding mechanism, indicatedgenerally by the numeral 26, as hereinbelow described. It will be notedthat only one side of the bed is illustrated, since both sides aresymmetrical.

The head section 26 comprises a pair of similar symmetrical side members27 of angle iron, each comprising a flange 27a and a flange 27b at rightangles thereto and in a vertical plane. Each member 27 has securedthereto an upwardly-extending rear bracket 28, to which said other endof side member 25a is pivoted as by pivot pin 30. Located forwardly anddownwardly of the pivot pin 30 in side member 25a, is a pin 30a to whichis pivoted one end of a link member 30b. The rear ends of flanges 27aare interconnected by a transverse member 32 of angle-shaped crosssection riveted thereto. The forward. ends of members 27 areinterconnected by a transverse tube 33 flattened at its ends and rivetedto the flange portion 27a thereof. The flanges 27a are formed withopenings in which are hooked ends of coil tension springs 34 connectedby wires 35 in the usual manner to form a spring.

The flanges 27b are provided with slots 30C through which pins 30d,secured to the outer end of link members 30b extend.

Riveted or otherwise secured against the outer side of each flange 27ais an outwardly-extending lug 38 formed with an opening 39 for thepurpose hereinafter described.

Attached to the inner side of the front lower portion of each side wall15 is a plate 45. Pivoted to each plate 45 as at 46 is a bent bar 47.Bar 47 extends upwardly and forwardly when the bed is extended. The bar47 has a lower portion 4.8 contacting plate 45. At the upper end ofportion 48 is an inwardly offset portion 49 from which extends a portion50 parallel to and spaced inwardly of portion 48. Near the upper end ofeach bar 47 is an inwardly olfset portion 51 from which extends upwardlya portion 52 offset inwardly from portion 50. Attached to portion 52 andextending rearwardly thereof is a bracket 53 formed with an opening 54.At the end of portion 52 is another inwardly offset portion 52a fromwhich extends upwardly a portion 52b parallel with portion 52.

Interconnecting bracket 53 with portion 41 of member 38 is a coiltension spring 55 having hooked ends received in openings 39 and 54,respectively.

At the upper end of each bar 47 is a pivot 52e. Fixed to each member 27is a lug 52d projecting thereabove and carrying a pivot 52e. Connectingpivots 52e and 52e at each side of the bed is a link 52j. A bumpermember 52g having an outwardly offset and upwardlyextending portion withan inclined edge 52h is Xed against the side of each of links 52]c forthe purpose hereinafter appearing.

Pivoted to the front ends of members 27 as at 57, are the rear ends ofan intermediate section 58. The intermediate section 58 comprisesangular side members 59 having vertical flanges 60 and horizontalflanges 61. Flanges 61 of the side members 59 are likewiseinterconnected by coil tension springs 34 and wires 35 to form the baseor spring of the bed. The flanges 60 are formed with elongated slots 61anear their front ends for the purpose hereinafter appearing.

Each flange 60 is provided with a pin 60a to which a link member 60b ispivoted at one end against the inside of its respective flange. Theother end of each-link 4 member 60h is pivoted to respective ones of thepivot pins 30d.

At the forward end of each member 59 is a pivot 63. Pivoted thereto andextending down therefrom is an intermediate leg 64. Theleg 64 ispreferably of angular cross section and has an outer flange 65 and atransverse flange 66. Flange 60 of each member 59 carries a pivot pin 67located forwardly of the upper end of bent bar 47 when the bed isextended. Pivoted on said pivot pin 67 f is a lever 68. Said lever 68has an arm 69 projecting upwardly and rearwardly and pivoted to thepivot pin 52C. Said lever 68 has a downwardly and forwardly projectingarm 70 carrying a pivot pin 71 at its lower end.

The outer ilange 65 of leg 64 carries pivot pin 72 below the pivot pin63. Interconnecting the pivot pins 71 and 72 on each side of the bed, isan angular link 73. Fixed to said link and projecting inwardly therefromis a pin 74 which rides in a longitudinal groove 75a in one end of alink member 75 comprising part of a locking mechanism hereinbelow morefully described. The other end of link member 75 is secured to a pin75l: which rides in the slot 61. When the bed is extended the pin 74 isdisposed below and substantially centrally located with respect to theslot 61, and the pin 74 is approximately centrally located in the slot75a.

Fixed to the outer ange 65 of leg 64 andprojecting outwardly therefromis a stop pin 76. Stop pin 76 is located below the pivot 63 and abovethe pivot 72.

At the front end of the intermediate or main section 58 is a short foldsection 80. Section 80 comprises a pair of angle shaped members 81, oneon each side of the bed. Each member 81 has a horizontal ange 82 fromwhich extends upwardly a vertical ilange 83. The rear end of each flange83 is pivoted to the pivot pin 63. Each flange 83 is furthermore formedwith a short slot 84, for the purpose hereinafter appearing. Connectingto the flanges 82 are coil tension springs 34 interconnected by wires 35forming part of the spring base of the bed. The flanges 82 of members 81at opposite sides of the bed are interconnected vby a cross brace bar86.

At the front end of the short fold section is the foot section 90. Saidfoot section comprises a pair of similar symmetrical angle shapedmembers 91 one at each side of the bed. Each member 91 has a verticalilange 92 and a horizontal ilange 93. The rear end of each flange 93 ispivoted to the front end of flange 83 of member 81 by pivot pin 93a. Thefront ends of anges 93 are interconnected by a transverseinterconnecting member 94. Said flanges are further interconnected by atransverse member 95 disposed somewhat rearwardly of the transversemember 94. Member 95 is secured below the flanges 93.

Pivoted to the outer flange 65 of each leg 64vas at 96 is a stop arm 97projecting upwardly and inclined forwardly when the bed is extended. Thearm 97 may have a notch 98 on one side edge thereof (or on both sideedges so that the left and right bars may be interchanged). The purposefor the notch 98 will be explained hereinafter.

At the upper end of arm 97 is a pivot pin 99. Pivoted to the pivot pin99 is one arm 100 of a bell crank 101. Carried by the intermediateportion of the bell crank 101 is a pivot pin 102 which passes throughthe slot 84. Said bell crank 101 further comprises a downwardly andforwardly projecting arm 104 formed at its underside with an inwardlyturned flange 105 disposed below the flange 82 of member 81. The pivotpin 102 is at the forward end of slot 84 when the bed is fully extended.

Flange 92 of member 91 carries a pivot pin 107 located forwardly of thepivot pin 93a. Pivot pin 102 is connected to said pivot 107 by link 108located at the inside of flange 92. Carried by the link 108 adjacent tobut spaced from the pivot pin 102 is a pivot pin 110. Interconnectingthe pivot pins 7511 and 110 is a link 111 located at the inside of theflanges 60 andy 83 and` saidi link 108. Attached to the outer side offlange-83 and adjacentthe pivot pin 93a is an angle shaped bracket 115comprising a Vertical wall 116 from which extends outwardly a horizontalflange 117. Flange 116 is xed to said flange 83. The ilanges 117 ofmembers 115 at opposite sides of the bed are interconnected by a board120v adapted to rest edgewise on the top edge of the usual front boardwhen the bed is fully collapsed, as will be explained hereinafter.

Connected to the flange 93 are also a plurality of members 34interconnected by wires 35 and forming a continuation of the bedsprings. Pivoted to the flanges 92 of members 91 rearwardly of the crossbrace 95 as on pivot 122, is a foot leg 123. Said foot leg carries apivot pin 125 just below pivot 122. Fixed to the ilange- 83 and wall 116of member 115 is a pivot pin 126. Pivot pins- 126 and 125 areinterconnected by link 128 which is substantialy horizontal when the bedis fully extended.

It will be understood that a mattress (not shown) is placed on the wires35 and over the cross springs 34. When the bed is collapsed in themanner hereinafter explained, the mattress is folded with the bed. Itwlll be noted that the portions of the bed forwardly of the bell crankor lever 69 have no obstructions or projections extending above the sidemembers 58, 81 and 91. This portion of the bed is generally referred to-as the sitting port-ion of the bed and the fact that there are noobstructlons atV that location is an advantage, as it allows people tosit on the bed in comfort.

The outer ends of the side flanges 92 of the members 91 each havesecured thereto a bumper member 128a adapted to abut the respectivebumper members 52g when the bed is in folded condition as will beapparent from the following description. A transverse foot bar 1.30a islocated between the upper ends of upwardly extending members 130b fixedagainst the outer ends of the members 91. The foot bar 130ay is securedto side arms 130c`having outer ends pivoted to the members 130b so as tobe foldable inwardly against the mattress when the bed is folded up, asillustrated in Fig. 4.

It will be noted that when the bed is fully extended, van upward lift atthe foot of short fold section 80 to fold upwardly relative to the frontend of the main or intermediate section because of the engagement of thellanges 105 of bell crank 101 with the undersides of the flanges 82 ofmembers 81 of said short fold section. The reason for this is that whenthe bed is fully extended the ilanges 105 contact the undersides ofanges 81. ln fully extended position the arms 97 are inclined forwardlyand upwardly, but the angle which these arms makes with a vertical linepassing through the pivot 96 is less than the angle formed by a linepassing through the pivot pins 63 and 99 and .a Vertical line passingthrough pivot pin 96. For this reason if the short fold section was tospring upwardly about the pivot pin 63 lfrom the fully extended positionof the bed, arms 97 would have to move in a clockwise direction, whereasthe bell crank 101 would have to move in a counterclockwise direction.But the bell crank cannot move in a counterclockwise direction becauseof the engagement of the flanges 105 with the underside of the flanges82. For this reason an upward pull on the front end of the foot sectionwould result in only the foot section moving upwardly from the positionshown in Fig. 1 to the position shown in Fig. 2 and during such movementthe short fold section remains in horizontal position.

As the foot section 90 is swung upwardly, members 91 pivot upwardlyabout the pivot pin 93a. During such action the foot leg 123 swings in aclockwise direction against the underside of the foot section. Suchaction is caused by the link 128. Furthermore as said foot section isswung upwardly, the pivot pin 102 on which bell crank 101 rotates, andwhich is connected also to the the bed will not cause the lll link 108,slides to the left in slot 84. At the same time arm 97 swings in acounterclockwise direction yuntil the notch edge of said arm contactsthe stop pin 76 and brings the pivot pin 99 in direct axial alignmentwith the, pivot 63. Thus the distance of the center of pivot pin 96 fromthe center of pivot pin 99 is exactly equal to the distance between thepivot pin 96 and the pivot pin 63. As the foot section is swungupwardly, furthermore, links 108 will swing upwardly about pivot pins102. When the pivot pin 102 is at the left end of the slot 84, members91 of the foot section 90 will have swung slightly past the vertical.Since the link 108 swings in a counterclockwise direction about thepivot pin 102, the pivot pin 110 will be raised and the pivot pin 75htogether with link member 75 will travel to the left in slot 61, butonly about half way through said slot. The link member 75 will thus becaused tor swing counterclockwise and downwardly with respect to pin 74,so that pin 74 is disposed in the upper end of slot 75a as illustratedin Fig. 2. At this time, further swinging movement of the foot sectionwill cause the short fold section 80 to swing upwardly therewith aboutthe co-aligned pivot pins 63, 99. Now the short fold section can swingupwardly about pivot 63 because the bell crank 101 can swing about theaxis of the pivot pin 63. Thus the foot section 90 of the short foldsection 80 can be swungfrom the position shown in Fig. 2 to the positionshown in Fig. 3,.

It will be noted that when the foot section has been swung upwardly andthe bell crank 101 has slidably moved to the left to bring the pivot pin102 from the right end of slot 84to the left end of said slot, said bellcrank will swing in a clockwise direction, thus moving the ange 105 awayfrom the underside of the flange 82 of member 81.

When the foot section 90 is swung from the position of Fig. 2 to theposition of Fig. 3 the bell crank 101 will swing upwardly about thepivot pins 99 to bring the arms 100 of said bell cranks substantially inalignment withy the arms 9.7. During such. motion, furthermore, thepivot pin 110 moves upwardly while the pivot pin h slides all the way tothe le'ft end in slot 61 and the link 111- rotates in a counterclockwisedirection. Such movement rotates the link member 75 counterclockwiselyto such an extent that the end of its slot 75a contacts the pin 74. Thefact that the pivot pin 102 is at the left end. of the slot 84 preventsthe foot section from further rotating relative to the short foldsection in a counterclockwise direction.

It willl be noted, furthermore, that in the position of Fig. 3 the footsection 90 cannot be raised relative to the short fold section becauseto do so pivot pin 102 would have to ride up in the slot 84. But thatcannot be done, because arm of bell crank 101 is in alignment withk thearm 97 and said arms cannot be extended. It will be noted that amattress placed on. the extended bed will have its foot end foldedupwardly with the foot section. of the bed and then said foot end of themattress will be folded over the intermediate portion of the mattress asthe bed is folded 4from the position of Fig. 2 to the position of Fig.3., so that two layers of mattress are then between sections 58 and 90of the bed.

To now complete the final phase of the full collapsing of the bed, theboard may be grasped and the front end of the bed pulled up somewhat andthen pushed rearwardly, causing the bed to move from the position ofFig. 3 to the fully collapsed position of Fig. 4. During such movementthe head section 26 will swing 90 in a clockwise direction about thepivot pins 30 in right angular side members 25a, and said side memberswill at the sameA time swing clockwisely about their pivot pins 25. Saidhead section will thus swing through a resultant angular movement of 90,bringing the head section to a vertical position extending downwardlyfrom the end of right angular side members 25 and bringing the rpivotpin 57 which connects the head section with the intermediate or mainsection down to the lower rear end of the frame 11. During such actionthe links 52f which interconnect the pivot pins 52e with the pivot pins52e` at the upper ends of the bent bars 47 will cause said bars to swingin a counterclockwise direction from the position of Fig. 3 to theposition of Fig. 4. Such rotation of the bars 47 will cause rotation ofthe lever 68 about pivot pin 67. Actually the levers 68 rotate in aclockwise direction about pivot pin 67. Members 59 of the intermediatesection 58 move to a substantial horizontal position aligned with thepivot pin 57 so as to lie rearwardly of the front board of the frame.Swinging movement of the lever 68 causes the angular links 73 to bepulled to the left thereby causing the intermediate leg 64 to rotate ina clockwise direction about the pivot pins 63. During such movement thelinks 73 will be moved rearwardly and toward the level of members 58.The angular links 73 will move upwardly and forwardly so that their pins74 are at rear positions in the slots 75a in link members 75, therebyblocking movement and press them towards the front of the link 111 andpreventing the opening up of the bed in its collapsed condition. Thus,when the pins 74 are in their rearmost positions in their slots 75a, itis not possible t-o swing the short fold section relative to theintermediate or main section, nor is it possible to swing the footsection upwardly relative to the short fold sections. Swinging of theshort fold section clockwise relative to the main or intermediatesection in the position of Fig. 4, is prevented by reason of the factthat to do so would require the pin 75b t-o slide to the right in theslot 61, and this is not possible because of engagement of the pin 74with the inner end of its slot 75a in link member 75. The foot sectioncannot be swung upwardly, furthermore, because to do so would requirethe pivot pin 102 to ride up in the slot 84 and that is not possiblebecause said pivot pin is connected by the bell crank 101 with the pivotpin 99 disposed directly therebelow.

The springs 55 are stretched during the full collapsing of the bed so asto aid in extending the bed or moving the bed back from the position ofFig. 4 to the position of Fig. 3. In the fully collapsed position theboard 120 comes down on the top edge of the front board of the frame.

During the movement of the bed from the position of Fig. 3 to theposition of Fig. 4, the intermediate or main section4 58 rst tiltsdownwardly and rearwardly as the leg 64 moves up against the undersideof said main section, and it is during this movement of said mainsection together with the fold section 80 and the foot section 90 downinto the frame 11, that the pin 74 gradually moves upwardly andbackwardly in the slot 74a to lock pivot pin 75]; against the forwardend of the slot 61.

It will further be noted that when the bed is in folded condition, itwill not be possible when unfolding the bed, to move the main sectioncounterclockwisely relative to the head section because of the pin 30d.The inner end of the link member 30b is moved all the way up in its slot30C so that its pin 30d abuts the end thereof.

As can `be seen in Fig. 4, when the bed is in folded condition thebumper member 128 will rest against its cooperative bumper member 52g soas to provide a firm support for a cushion and to minimize thepossibility of any harm being done to the folding mechanism during hardusage of the convertible bed as a sofa or couch.

Figs. l0, 1l and l2 illustrate a modification of the bed foldingmechanism illustrated in Figs, l through 9 wherein the cross brace bar86, instead of being connected directly etween the llanges 82 of members81 of the short fold section 80, is instead interconnected betweenflange portions 130 of an angle iron link member 131 extendingdownwardly of said short fold section when the bed is in extendedcondition. By means of such lowering of the cross brace bar 86, thepossibility of it interfering with the loweringof the bed springs whensitting over the short fold section is eliminated. The modiedconstruction dilfers from the mechanism described above in connectionwith Figs. l through 9 in that the board 120, instead of being fixedwith respect to the short fold section 80, is interconnected therewithby means of a downwardly-extending bracket member 132 fixed against theflanges 83 of members 81, the link member 130 pivoted at one end to saidflange member by a pivot pin 133, and an angle member 134 having aflange 135 to which the other end of link member 131 is pivoted as by apivot pin 136. The board 120 is fastened between anges 137 of the anglemembers 134 at each side of the bed. The cross brace bar 86, beingconnected between the ange portions 130 of the angle iron link members131, is thus located far enough below the bed springs so as not tointerfere with comfortable sitting over the short fold section.

Parallel guide mechanism is also provided for drawing in the mechanismsupporting the board 120 together with the cross brace bar 86 when thebed is folded, as is illustrated in Fig. 12.V Said mechanism comprises alink member 138 having one end pivoted to the pivot pin 136 and havingits other end pivoted to pm 102 which, as described above, slidesrearwardly in slot 84 when the foot section is moved upwardly withrespect to the short fold section when the bed is being folded. Anotherlink member 139 interconnects the rear end of angle member 134 with theange 83 of the short fold section, being pivoted to said members as bypivot pins 140, 141.

As can be seen in Fig. l2, when the bed is folded, the movement of thelink member 138 rearwardly as described above, will result in the board120 being drawn in closely parallel to the short fold section framework,and the link member 131 will be rotated to extend parallel with the sidemember 81 of the short fold section. The cross brace bar 86 will thusalso be drawn up close to springs `of the short fold section when thebed is folded, to provide a compact structure having the board 120vertically aligned with the front board of the sofa frame.

It will be noted that the foot section 90 and short fold section becomefully locked to the intermediate section 58 about half-Way from theposition of Fig. 3 to the position of Fig. 4 (as the bed is beingcollapsed and moved towards its fully collapsed position). The lockingtakes place when the pin 74 reaches the left end of slot 75a, and link75 swings in a counterclockwise direction, looking at Fig. 3, to aposition where said pin 74 is horizontally aligned with pin 75b. Theadvantage of this locking action in advance of full collapse, is thattl'iel foot section is held down and prevented from hitting theupholstered back of the sofa, and also the foot section is preventedfrom being pushed open by the mattress which is folded between the footand intermediate sections.

In Fig. 13, there is illustrated a modified construction. The bed, asshown in Fig. 13, is the same as the bed shown in Figs. 1 to v12, withthe exception that the link 75 is replaced by a link 150 formed with aslot 151 which corresponds to the slot 75a of said link 75.

The slot 151 is shorter than the slot 75a at the end remote from thepivot pin 75h. By shortening said slot, the movement of the bed fromfully collapsed position of Fig. 4 to the position of Fig. 3 will serveto lift the foot section, because the pin 74 pushes the link 150 downand to the right, causing pin 75b to move to the right in slot 61a;thereby moving link 111 up and to the right; thereby swinging link 108up, tending to rotate it in a clockwise direction and hence to lift thefoot section to an inclined position. The advantage of this opening up`or lifting of the foot section when the bed is moved from fullycollapsed position to a position corresponding to Fig. 4 is that theoperator would not have to lean all the way over to pick up the foot 9section forv swinging the foot and fold sections to fully opened upyposition. However, the opening up of the foot section 90 should not toogreat since if it were allowed to open up too much, it might hit theupholstered back of the sofa.

It will thus beseen that there lis provided a device in which theseveral objects of this invention are achieved and which is well adaptedto meet the conditions of practical use.
